How powerful was the Saturn rocket that boosted the Apollo missions into low Earth orbit? So powerful even the models for the Saturn rocket boosters produced hundreds of pounds of thrust for every engine.

This Saturn I booster model was set up for tests in the Supersonic Wind Tunnel in 1960, simulating flight conditions to better understand the vehicle’s potential issues with stability and air pressure distribution. Even for the model, each of the eight engines was powerful enough to produce 250 pounds of thrust.
